Ophanim Bike (functionally identical to a Space Marine Bike, but sleeker looking and property of the Adepta Sororitas)

Special Rules:

Acts of Faith

Shield of Faith

Grace of the Emperor -- This Act of Faith gives the unit Hit & Run and Skilled Rider if the test is passed. I think the prevailing theme of Acts of Faith dictates they only last for a phase, so you'd have to use a Faith Point and test the beginning of each phase you want to use it (so if you want the Jink bonus from Skilled Rider, you need to use it at the beginning of opponent Shooting). The next real Sisters codex could use some Acts of Faith/Faith Points refining. You get the same number of Faith Points regardless of whether you have a minimum sized 200-300 point ally detachment or you're doing a 3000 point Apocalypse battle.
